We study one-dimensional chains of billiards, where it is possible to switch between order and disorder in two respects: regular versus chaotic scattering in the billiards, and periodic versus random length sequence of the connecting pipes. Classically, the dynamics is largely dominated by the type of the scatterers. Quantum mechanically, the connector length sequence is also decisive: there are extended states and a band spectrum if it is periodic, whereas if it is random, states are localized and the spectrum is discrete. In this case, the spectral statistics forms a transition between GOE (for short chains, compared to the localization length) and Poissonian (for very long chains) and can be related to the way a corresponding classical ensemble explores phase space.
